ARM: dts: rzg1: Add generic compatible strings to IIC nodes

Browse Source 
According to the Hardware User's Manual, automatic transmission for PMIC
control (DVFS) is not available" on RZ/G1 SoCs.  This really means that
support for automatic DVFS is not present, while the IIC automatic
transmission feature itself is still available, albeit not super useful.

Hence there is no longer a reason not to declare compatibility with the
R-Car Gen2-specific and generic versions.
